About the Role
We’re looking for a Senior React/Java Full Stack Developer with strong expertise in React front‑end development and hands‑on Java experience. This is not a senior back‑end Java role. You will join our high‑performing team building our Internal Developer Portal that accelerates software delivery across the enterprise. It’s a fast‑paced, high‑impact role where you own features end‑to‑end — from React front‑ends to Spring Boot microservices — and ship code that developers depend on daily.
What You’ll Do
Backend (Spring Boot / Java)
- Design, build, and operate Spring Boot 3 microservices (Java 17/21) within a distributed architecture that includes event orchestration, event processing, notification, work‑item tracking, file upload (AWS S3), and service discovery (Eureka).
- Own database schema evolution using Liquibase against PostgreSQL, and write performant JPA/Hibernate queries with HypersistenceUtils for advanced column types.
- Implement and extend our custom workflow/flow engine built on Spring Integration, including authoring reusable event tasks (Git, GitHub Enterprise, Jira, SSH, email) and worker services.
- Harden security across services using Spring Security, OAuth2 (client+resource server), JWT (jjwt), AzureADSSO, and HashiCorpVault for secrets management.
- Build and maintain the API Gateway (Spring Cloud Gateway WebMVC) that fronts all backend services.
- Produce clean, self‑documentation APIs with Springdoc OpenAPI (Swagger UI) and HATEOAS where appropriate.
Frontend (React / TypeScript)
- Develop and ship features across a Turborepo monorepo containing multiple single‑page applications using React19, TypeScript, and Vite.
- Build rich, accessible UIs with MaterialUI, Material React Table and D3‑based data visualizations.
- Manage client‑side state with Zustand and TanStackReactQuery; consume both REST and GraphQL APIs (URQL).
- Write thorough unit tests with Vitest+TestingLibrary and end‑to‑end tests with Playwright; maintain high code coverage via V8 coverage reporting.
Cross‑Cutting
- Champion code quality through peer code reviews, Checkstyle, Spotless formatting, SonarQube analysis, and JaCoCo coverage gates.
- Ship containerized services via Docker multi‑stage builds, Helm charts, and Jenkins CI/CD pipelines targeting OpenShift (ROSA), with integrated NexusIQ, Twistlock, and Polaris security scanning.
- Write comprehensive JUnit5 unit tests, Spring Boot integration tests, and WireMock‑based service tests on the backend; maintain Playwright E2E suites on both Java and JavaScript sides.
- Collaborate closely with product owners and fellow engineers in an agile environment with frequent release cadences.
- Mentor and guide junior developers, drive technical decisions, and contribute to architecture discussions for a platform that is actively scaling.
Qualifications
Must‑Have
- 8+ years of professional software development experience with a strong full‑stack track record.
- Deep hands‑on expertise with Java17+ and the Spring ecosystem (Spring Boot3, Spring Security, Spring DataJPA, Spring Cloud).
- Production experience building modern React applications with TypeScript, including state management (Zustand, ReactQuery, or equivalent) and component libraries (MUI or similar).
- Solid understanding of relational databases (PostgreSQL), schema migration tools (Liquibase or Flyway), and ORM frameworks (Hibernate/JPA).
- Experience with RESTful API design, OpenAPI/Swagger, and at least working knowledge of GraphQL.
- Proficiency with containerization (Docker), CI/CD pipelines (Jenkins, GitHub Actions, or similar), and Kubernetes or OpenShift deployments.
- Strong testing discipline — you write unit, integration, and E2E tests as a matter of course (JUnit5, Vitest, Playwright, WireMock).
- Undergraduate degree in Computer Science or any equivalent combination of education and experience.
Nice‑to‑Have
- Experience with Spring Cloud Gateway, Netflix Eureka, or similar service‑mesh/discovery patterns.
- Familiarity with Helm chart authoring and OpenShift/ROSA operations.
- Hands‑on experience with HashiCorpVault, OAuth2/OIDC flows, and AzureAD integration.
- Exposure to monorepo tooling (Turborepo, pnpm workspaces) and build optimization (Vite, SWC).
- Experience with workflow/orchestration engines or Spring Integration.
- Comfort with MkDocs, Storybook, or other developer‑experience documentation tooling.
- Familiarity with AWSS3 and the AWS SDK for Java.
Who Thrives on This Team
- You take initiative and run toward problems, not away from them.
- You communicate clearly and directly — in PRs, in design docs, and in person.
- You’re energized by fast iteration, tight deadlines, and the accountability that comes with shipping a platform other teams depend on.
- You care deeply about code quality, developer experience, and leaving the codebase better than you found it.
- You’re comfortable context‑switching between backend and frontend work within the same sprint.
- For candidates located in Quebec, bilingualism is required to interact regularly with English‑speaking colleagues across the country.
